Aflat dance floor of dimensions l(x) = 17m by l(y) = 19 m has a mass m = 1400 kg. use the bottom left corner of the dance floor as the origin. three dance couples, each of mass m = 110 kg start in the top left, top right, and bottom left corners.

part one:
a. what is the initial y coordinate of the center of gravity of the dance floor and three couples? answer in units of m.

part two
b. the couple in the bottom left corner moves 7.6 m to the right. what is the new x coordinate of the center of gravity? answer in units of m.

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?
